Rails - Apr 2005 - RE: error handling

Hi Patrice, 

I''m going through this process of handling
"ActiveRecord::RecordNotFound" in my code, and your approach is the
cleanest I have found so far.

Thanks for posting,

Neville

Subject: [Rails] error handling

Hi,

I have recently started using Rails and am currently digging into it as
well as Ruby.

Now I was wondering how to best handle RecordNotFound errors with
showing a nice 404 page and still not writing too much code. I came up
with a method in the ApplicationController and calling that method with
a block.

The method looks like this:
  def handle404(pagetitle)
    begin
      yield
    rescue ActiveRecord::RecordNotFound
      @page_title = pagetitle
      render "layouts/error", 404
    end
  end

And I call it as follows:
  handle404("Project not found") {
    @project = Project.find(@params["id"])
    @page_title = "Project: " + @project.title
  }

See also my German explanation of this approach at
http://patrice.kaywa.ch/ruby_on_rails/fehler-behandlung_in_rails.html

Is this a practical way of doing this stuff? How do you generally do
this?

Patrice
